Hassan Sheets and Plate is a reliable Riyadh-based Saudi manufacturer and supplier of high-grade metal products. A firm commitment to precision, strength, and customer satisfaction has earned the company a trusted reputation in the market. Among their wider range of products, Duplex Steel S31803 Channels are particularly known for their superior performance even in harsh conditions. These channels are designed to strict industry standards and are well suited for a vast range of industrial uses in construction, petrochemical, and marine industries where corrosion resistance and high strength are essential.
Duplex Steel S31803 Channel consists of around 22% chromium, 5–6% nickel, and 3% molybdenum, with a balanced microstructure of austenite and ferrite. The composition is excellent for corrosion resistance, especially against stress corrosion cracking and pitting. Mechanically, it has a tensile strength of approximately 620 MPa and a yield strength of approximately 450 MPa, with good impact toughness and ductility. Its resistance to conditions of harshness makes it an ideal choice for structural work in harsh environments where other stainless steels would fail.
